WINDMILL.

SPECIFICATION forming part of Letters Patent No. 262,058 dated August 1,1.882.

t Application filed May 19, 1882, (No model.)

To all whom it may concern Be it known that I, CORNELIUS KUNKEL, ofOregon, in the county of llolt and State of Missouri, have invented anew and useful Improvement in Windmills, of which the following is afull, clear, and exact description.

The invention consists of the application of a vane or vanes towindmills in a manner to counterbalance the tendency of the wind tochange the angle of the vanes of the wheel, so that a governor employedto regulate the said angle will be relieved of the duty of holding thevanes to the wind and will only he required to shift the angle of thevanes as the wind varies, the tendency of the wind to shift the vanesbeing counterbalanced by the equalizing-vanes of my invention at alltimes and in all positions, as hereinafter fully described, and pointedout in the claim.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of a windmill with my improved equalizing-vanesapplied, a part being in section; and Fig. 2 is a side elevation of thesaid windmill with a part sectioned.

A represents the shaft of the wind-wheel, which is mounted in hearings Bof' the turntable 0, and carries the vanes D, which are pivoted to thehub E atF, and are connected by crank G to the ring H, which isconnected by rods I to the hub J, mounted onthe shaft so as to. slidetoward and from the vanes, said hub being connected by forked head K ofrod L to the toothed yoke M, which is gearedwith pinions N, to which Iapply the equalizingvanes O by attaching the stems R of said vanes tothe hubs or shafts of the pinions, the pinions being mounted on theturn-table each side of the shaft, at the rear end, or at a distanceback from the turn-table on the stem to the main vane and the vanes O,ranging forward therefrom nearly to the vanes of the wheel and slightlydivergent from the shaft when the wheel is at rest. The equalizingvanes,being mounted on long arms, have such leverage that comparatively smallvanes O will be equal to the larger areas of the vanes D for the purposerequired ,-which is to equalize or balance the vanes D in whatever angleto the wind they may be adjusted by the regulator. The said vanes O areso geared with vanes D as to oppose the tendency of said vanes D to beturned on their axes-F by the wind. They are to be so adjusted as totheir leverage and with respect to the vanes D that they will balancevanes D in whatever position the latter may be caused to assume by thegovernor or other device employed to determine the angle of said vanesto the wind, no matter how much the wind may vary because of thecounteroalancing effect of the one on the other, both being alikesubject to the variations of the wind, so that the governor employed toregulate the speed of the wheel by centrifugal weights or other devicesis relieved of stress by the wind, and has only to overcome the frictionof the parts in regulating the speed, and thereby is more sensitive andeffects greater regularity of motion. I have represented two vanes, O,in this example, which is the arrangement that I prefer, and they arelocatedon opposite sides of the shaft; but they may be arranged aboveand below; or I may use only one, placing it either above or below theshaft. With the pinion and yoke arrangement the equalizing-vanes mayswing round to or nearly to the tail-vane Q.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In a windmill, the combination, with the hub E, the vanes D, pivotedthereto and provided with the cranks G, the sliding ring H, the rods I,and the hub J, of the forked head K, the rod L, the toothed yoke M, thepinions N, and the equalizing-vanes O, substantially as and for thepurpose set forth.

CORNELIUS KUNKEL.
